Reliable and durable

We have had this installed for six months in a high-traffic retail store. It shows no signs of wear and maintains consistent closing speed regardless of how hard the door is pushed. Great value for an authorized product.

Professional grade equipment

As a contractor, I install many floor springs. The S-2400 is one of the easiest to calibrate and holds its setting over time. The official authorization gives peace of mind regarding authenticity.

Perfect for heavy glass entrance

Installed this on our office main entrance which uses thick 12mm glass. The 180kg capacity handles it effortlessly. The closing action is smooth and silent. Highly recommended for commercial use.

Good for universal profiles

Fits standard glass door profiles as advertised. The mounting plate is versatile. Just ensure your floor cavity is deep enough before purchasing. Overall a great heavy-duty solution.

Solid build quality

The unit feels very robust and the stainless steel finish matches our other hardware perfectly. Installation required some precision drilling, but the instructions were clear. One star off because the adjustment tool could be better included.

Smooth operation

Replaced an old hydraulic spring with this GMT model. The difference is night and day. No more slamming doors. The adjustable speed settings allow us to fine-tune it exactly how we like.
